In a copying apparatus, a storage capacity of an HDD which is used in a unique file system can be changed. In a partition area for image data formatted by a general-purpose file system, an area for a virtual unique high speed file system is provided and a reservation file having a data structure which can be used by the unique file system is constructed. A unique high speed file system accesses such an area, thereby enabling functions of the unique high speed file system to be virtually used and enabling information management of the image data to be made.
